Question

The polygons are similar, but not necessarily drawn to scale. Find the value of x.

Answer 1

the ratio of corresponding sides of similar polygons is a constant.

Here, the corresponding sides are 20 and 39, and 5 and \(x\)

just form the ratios, equate them, solve for the unknown \(x\)

Answer 2

how do i do that? sorry i suck at geometry.

Answer 3

The equation for ratios in this case is \(\frac{AD}{JM} = \frac{CD}{LM}\). Since you know that they are similar, it means that their side's ratios will be the same.

Answer 4

these are the answer choices • 9.75
• 11.8
